The Short Form of the Revised Almost Perfect Scale

Abstract

We created a shorter and more refined item set from the Almost Perfect Scale-Revised (APS-R; Slaney, Mobley, Trippi, Ashby, & Johnson, 1996; Slaney, Rice, Mobley, Trippi, & Ashby, 2001) to measure 2 major dimensions of perfectionism: standards (high performance expectations) and discrepancy (self-critical performance evaluations). In Study 1, after testing the internal structure of the measure (N = 749), a subset of the current APS-R items was derived (Short Almost Perfect Scale [SAPS]) that possessed good psychometric features, such as strong item-factor loadings, score reliability, measurement invariance between women and men, and criterion-related validity through associations with neuroticism, conscientiousness, academic performance, and depression. Controlling for neuroticism and conscientiousness, factor mixture modeling supported a 2-factor, 3-class model of perfectionism, and results were consistent with labeling the classes as nonperfectionists and adaptive and maladaptive perfectionists. Measurement results were cross-validated in a separate sample (N = 335). Study 2 also provided substantial evidence for the convergent, discriminant, and criterion-related validity of SAPS scores. Both studies supported the SAPS as a brief and psychometrically strong measure of major perfectionism factors and classes of perfectionists.

Is the “Almost Perfect Scale” Almost Perfect? The Psychometric Properties of the Arabic Version of APS-R and Its Short Form

“…The discrepancy and standards subscales were partially invariant across groups but strongly (not strictly) invariant between genders in the combined group. Psychology We further compared the Arabic adapted short version of the scale (Rice, Richardson, & Tueller, 2014) …”

“…We will present the reliability and validity estimates of the Arabic version of the APS-R in the results section. Additionally, we used the eight items short measure (APS-R-S), that was derived from the same items pool (Rice, Richardson, & Tueller, 2014), that proved to have adequate validity and reliability in the English version. The short measure includes only standards and discrepancy subscales.…”

“…Further, a short version of the scale that includes 8 of its items and represents standards and the discrepancy was tested and found to have similar characteristics (Rice, Richardson, & Tueller, 2014).…”

How Should Discrepancy Be Assessed in Perfectionism Research? A Psychometric Analysis and Proposed Refinement of the Almost Perfect Scale–Revised

“…The current findings also have possible implications in terms of evaluating measures derived from the APS-R. Impressive work by Rice and associates has resulted in the development of a briefer version of the APS-R (see Rice, Richardson, & Tueller, 2014).…”

Brief Differential Perfectionism Inventory:Checking Cross-Cultural Stability of the Factor Structureand Psychometric Characteristics

“…Perfect Scale, APS) один из авторов теста спустя годы психометрических проверок сократил с 23 пунктов до 8, причем последние диагностируют сразу две под-шкалы: стандарты (личные эталоны достижений, или позитивный фактор перфекционизма) и расхождение (ощущение несоответствия между реальностью и соб-ственными ожиданиями, или негативный фактор пер-фекционизма) [19]. В настоящей статье описана разработка и кросс-культурная оценка краткой версии Дифференци-ального теста перфекционизма (ДТП) на русском и английском языках.…”
